Playing Moon Base
1st life get over 900 points on first wave
seems to end the game.
The game stops and a message scrolls out
from the right that says: You are too strong
The game them shows game over, then back
to attract mode. I don't see any documentation
about this.

It works fine in version 244. Stops working correctly in 245.
If someone wants to report it to mame testers.

Thanks with narrowing the search to find when the emulation bug first appears. And hap has fixed the issue.

That would have been something had it been some unique hardware protection booby trap that finally became exposed like the coinop cabs of Atari Tempest and their protection checks that were eventually discovered and documented.

Congrats to both for either stumbling upon the hardware protection check or to hap for fixing the issue and considering it may have been a protection check routine finally unearthed and documented just like one of those long hidden programmers ‘Easter egg’ codes coming to surface. A bit of trivia that might make its way to added info for the game sometime in the future.

rollingc: add comment for IN0 bit 0
https://github.com/mamedev/mame/commit/32f6f833cadc4c7b46f4977a29559ee36a3e1877
// bit 0: Looks like simple protection for moonbase, see routine at $0EB1, gets called at $0DD2.
// It checks for score overflow, and the game ends with message "YOU ARE TOO STRONG" when score
// overflows from 99990 to 0. If bit 0 value = 1, the game ends prematurely when score hits 1000.
